POWDER DUSTER.

Application filed .Tune 12, 1923. Serial No. 644,946.

To all whom t may concern:

Be it known that I, FELIX A. MooDY, a citizen of the United States, residing4 at Hahira, in the county of Lowndes and State of Georgia, have invented a new and useful Powder Duster, of which the following is a specification.

This invention has reference to a device especially designed for use in distributing poisonous powder employed for exterminating insects that usually infest vegetation.

The primary object of the invention is to provide a device of this character which will discharge a predetermined quantity of powder, novel means being provided for regulating the quantity of material discharged.

Another important object of the invention is to provide means that may be held in a position in proximity to the infested plant to insure against the wind blowing the powder from the plant, when the powder is being discharged from the container.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawings:

Figure 1 is a side elevational view of a powder distributing device constructed in accordance with the invention;

Figure 2 is a side elevational view disclosing the opposite side of the device;

Figure 3 is a sectional view taken on line 3-3 of Figure l;

Figure 4 is a detail view disclosing the upper portion of the container;

Figure 5 is an enlarged fragmental view y disclosing the guide for the movable rod employed for jarring the container;

Figure 6 is an enlarged detail view disclosing the adjusting means for the removable rod.

Referring to the drawings in detail, the reference character 5 designates the container which may be of any desired shape and size, however inthe present showing the preferred form is circular in cross section. Openings 6 are formed in the bottom of the container 5, through which openings the powder to be distributed passes.- Secured to the container and extending upwardly therefrom, is a frame 71 that includes the cross bar 8 formed with an opening 9, disposed intermediate the ends ofthe bar 8, which opening accommodates the vertically movable agitating rod 10. f

At the lower endof the rod 10 is a nut 11 operating on the threaded portion 12 lthereof, the nut providing a support for ythe coiled spring 13 that hasv one'end thereof engaging the upper surface of the nut as clearly shown by Figure 4 of the drawings. The upper extremity of the coiled spring 13 engages the under surface of the bar 8 to cushion the movement of the container when the same has been released by the tripping mechanism to be hereinafter more fully described.`

Positioned on the lower end of the rod l() is an arm 14 that extends laterally therefrom, and may, by movement of the nut 11 beadjusted longitudinally ofthe rod l() to tension the coiled spring 15, that has one endthereof secured to the outer extremity of the arm 14.

A bracket 16 is secured to the frame 7 and has a right angled upper extremity 17 formed with an opening to receive the eye bolt 18 on which operates the winged nut 19 to adjust the bolt 18 with respect to the bracket 16, the upper end ofv the coiled spring 15 being secured to the eye bolt 18.

The upper end of the rod l() is offset at 20 from where the same extends upwardly providing a section 21 terminating in a rightangled portion 22, providing a handle, by means of which the device may be supported by the operator.

Extending laterally from the frame 7 is a yoke indicated at 23 into which the lower end of the trip 24 extends, the upper edge of the trip bar being supplied with a.V roller 25. The trip bar is held in spaced relation with the rod 16, by means of the arm 26 which is formed with a slotted portion 27 designed to receive the bolt 28 supplied with a wing nut 29 so that the angle at which the trip bar 24 operates, may be adjusted to cause the device to be operated under varying springpressures, thereby regulating the quantity of materialbeing discharged from the container.

Connected with the lower end of the trip bar 24 is an operating bar 30 which has its upper extremity pivotally connected with the movable bar 3l that has pivotal connection with the upwardly extended portion 2l at 32, the opposite end thereof 4being forked at 33, which forked portion accommodates a guide rod 34 that depends from the handle portion 22. The lower end of the rod 34 is threaded as at 35 to accommodate the winged nut 36 which engages the movable bearing member 37 which in, turn engages the under surface ofthe forked extremity 33 to inove the bar 3l vertically, and adjust the tension of the spring 38 that is shown as connecting the bar 31 to ythe operating bar 30. The bar 3l may be supplied with a handle portion 39 which may be of rubber or other suitable material to prevent injury to the operators hand While the device is in use.

Formed on the inner edge of the bar 30 are teeth 4() that engage under the upper bar 41-1 of the framev causing the rod l() to move downwardly when the movable bar 3l is moved upwardly by the operators fingers,y the roller 25 at the upper end of thetrip 24- contacting with the lower extremity of the section 21 which in turn moves the lower extremity of the trip 24:

disengaging the teeth 40 from. the upper bar al of the frame..

lt is obvious that as the rod l0 moves downwardly, the spring l5 is placed under tension and when the teeth 40 are disengaged from the bar al, the coiled spring l5 returns the rod 10 to its normal position, causing a sudden jar of the container to the end that material held in the container will be shaken therefrom.

lit might be further stated that in order to securely hold the device, a handle l2 is provided,l which may be grasped by the left hand of the operator while the right hand is operating the bar 3l in a manner as described.

l claim l. In a device of the character described, a container, a vertical movable rod having connection with the container, means associated with the rod and container for holding the container stationary while the rod is being moved, and said container holdmeans adapted to automatically release the container, to permit the container to move over the rod, and means on the rod vfor restricting movement of the container.

2. ln a device of the character described` a container, a rod supported above the container and movable with respect thereto., means associated with the rod for holding the container while the rod moves with respect thereto, and said container holding 'means adapted to operate automatically to release the container., and resilient means fol` automatically Vmoving the container to its initial position.
